American revolution and the french revolution .explain why they were revolutions. how did they change and why did they change?

Well theyre both revolutions since the definition of a revolution is "a forcible overthrow of a government or social order in favor of a new system", I'll suppose you know the basics but the American revolution happened because there was problems between America and the British control over the colonies;the French Revolution happened because of the Monarchy issues which is another government relation. 

Outcome of American revolution/what it changed: more awareness to getting independence, and the major outcome was the Treaty of Paris, please do more study on your own about this as I've provided enough for you to write about.

Outcome of French revolution/what it changed: again more awareness for independence, ended the Monarchy then the French republic was made shortly after and the national state had more power, democratic French government was more on priority. 

Ithink it was the first election is which mass participation occurred.
